SOUND-REPRODUCING DEVICE.

SPECIFICATION forming part of Letters Patent N 0. 690,3 68, dated December 31, 1901.

I Application filed January 21 1898. Serial No. 667,466. (No model.)

- which the following is a specification.

My invention is directed particularly to a novel sound-reproducing device; and to this end it consists in constructinga record-blank of spherical form and combining therewith means for rotating the record and advancing the stylus thereover.

For a full and clear understanding of the invention, such as will enable others skilled in the art to construct and use the same, reference is had to the accompanying drawings, in which- Figure 1 is a side elevational View of my invention complete, and Fig. 2 is a sectional view taken through Fig. 1 on the lines a; w and as seen looking thereat from right to left.

A is the base, M the motor-box, and S the shaft connected to the motor and supporting the phonogram-blank, constructed, preferably, of wax and in the form of a sphere P.

The outer end of the shaft is journaled in a standard V, pivotally secured to the base A at p and provided with a lock or latch Z for locking it in its upper position. Y

'm and m are vertical standards provided at their upper ends with inwardly-extending trunnions t t. r

a aare the arms of a yoke to the upper surface of which is secured the diaphragnv supporting chamber N, 15 being the stylus, T the sound-conveying tube, and T the trumpet.

w w are counterweights secured by screwthreads to the lower ends of the arms a a, and f f are pivot-bearings adapted to support the arms a a upon the trunnions t t.

The operation of the apparatus is as follows: The standard V is unlocked and tilted to the left in the direction of the lower arrow and the record or phonogram-blank P placed in position upon the conical mandrel. (Shown in dotted lines.) The standardV is then restored to its normal position and locked by the latch Z. The diaphragm-chamber N and its attached parts, consisting of the diaphragm, (not shown,) and the stylus t, and sound-conveying tube T, and trumpet T, are then secured to the arms a a and the latter hung upon the trunnions t t in the extreme right-hand position, or so that the mouth of the trumpet is near the top of the motor-box, with the counterweights w 11; extending outward to the left. After the proper adjustment is attained between the stylus t and the record the motor is set in motion and the spiral -like nature of the record causes the parts to advance in the direction of the upper arrow, thereby correctly reproducing the sounds in a manner Well understood,the stylus t traveling always in a great circle of the spherical record and bearing, therefore, a con stant relation to the record.

I do not limit my invention to the special detail of construction hereinbefore described, and illustrated in the accompanying drawings, as I believe Iam broadly entitled to claim a phonographic record of spherical 'form, and my claims are generic as to this feature and also to a record of spherical form with means for rotating the same.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is Y 1. The improved record-blank for talkingmachines comprising a record-blank having a spherical surface.

2. The combination with a stylus in a soundreproducing machine of a rotary spherical record and means for causing the stylus to traverse the spherical surface of the record.

3. A phonograph or sound-reproducing device having a spherical-shaped record provided with means for rotating it about one axis of the sphere, in combination with areproducing stylus pivotally supported substantially at right angles to the axis of rotation, whereby the stylus is adapted to travel in the arc of a great circle on said spherical record.

4. A phonograph or sound-reproducing device provided with a spherical-shaped record, in combination with reproducing means so supported in connection with said record as to travel in the arc of a great circle thereof.

5. A phonograph or sound-reproducing device having a spherical-shaped record and log means for rotating the same, in combination I scribed my name this 20th day of January, wilth reproducing means so supported with 1898. re ation to the surface of the record that the stylus thereof will travel in a great circle CHARLES KIN PNER' 5 thereof, passing through the plane of its axis of rotation.

In testimony whereof I have hereunto sub- \Vitnesses:
